ICD-10 code for esophagus web

The ICD-10-CM code for esophagus web is Q39.4 (Esophageal web).

Within Q39 (congenital malformations of esophagus), Q39.4 is specifically for esophageal web. Related codes cover atresia of esophagus without fistula (Q39.0), atresia of esophagus with tracheo-esophageal fistula (Q39.1), congenital tracheo-esophageal fistula without atresia (Q39.2), congenital stenosis and stricture of esophagus (Q39.3), congenital dilatation of esophagus (Q39.5), congenital diverticulum of esophagus (Q39.6), other congenital malformations of esophagus (Q39.8) and congenital malformation of esophagus, unspecified (Q39.9).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 368 (Major Esophageal Disorders with MCC, relative weight 1.6433), DRG 369 (Major Esophageal Disorders with CC, relative weight 0.9922) and DRG 370 (Major Esophageal Disorders without CC/MCC, relative weight 0.6744), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
